A hardmetal ring is a size for size or low interference fit on the body of a disc cutter of a rock working machine, such as a boxhole borer. In one embodiment the ring is gable shaped and clamped between a fixed annular shoulder and a detachable annular shoulder. In another embodiment the ring is triangular in section and two annular shoulders resting on it and inclined surfaces on the body clamp the ring to the body.
